Right, depending on the type of game being developed, there is more than just programming involved with making a game. How many programmers here are actually good with crafting a story around a more RPG or episodic game? As well, how many programers are also good at managing members of the team, setting schedules for everyone to meet, and organize meetings to discuss future progress of the game?
If you haven't noticed, some large publishers run the same kind of format. They provide money and the ideas, and teams follow suit with a game that works. Teams consist of marketing, programers, sound designers, graphics artists, writers, voice actors, and whatever other role comes to mind.
The OP is at least not saying he wants to go on full dictatorial manager. He's willing to write the lore and script of the game, which depending on the type of game, can get involved. However, I actually suggest the OP to have work done onto the game before asking people on here for help. You need to have proof on what you are willing to do, and what direction the game should take. At minimum, having an outline of the lore/story ready to present, along with major details of the game world programers will be working in. If you have this already done, then start looking for people to help make this idea into a game. If not, work on that first and see who will be interested afterwards.
